RE: Formula or Isonic 155 lt.?

Hi Danilo,

Formula has more tail width, wider stance and harder rail, all of which improve the performance at lighter winds, early planing and upwind in combinattion with bigger FW fins and sails.
The iS155 has a narrower tail, slightly softer rails and an increase in control/comfort levels in choppy, more powered (by ~150Lt) conditions and an easier, more natural (for 150Lts ) jibe..

and let us know if you have any further questions you would like resolved.

Cheers ~ Ian

Formula or Isonic 155 lt.?

What are the main differences between Formula and I sonic 155 lt.; my weight is about 83 Kg and I sail normally with sails of 10-11 mq in lake at 90% of my time. Do You think that Isonic is faster then formula but more slow in early planning? Thanks. Danilo
